He floated like a butterfly, stung like a bee—and this is the story of one of the greatest boxers who ever lived, through the eyes of those who knew him and saw him fight. Muhammad Ali transcended sport to become a symbol of black pride, of principled opposition to the Vietnam War, and a world-famous figure. With his irresistible mix of bombast, comedy, innovation, and sublime talent, he brought boxing back to life, and this biography follows Ali from his humble beginnings to Olympic victory, through the “Rumble in the Jungle” and “Thrilla in Manila,” to his present-day battle with Parkinson's.
